Dark patch on Sony 49xd70o5

I have a Bravia TV which was bought in December 2016. It has always displayed some shading in the top right corner but this has become more noticeable over the last few months. The TV came with a 1 year shop guarantee. Is it still covered by a manufacturer's guarantee? What do I do? At £600, I can't afford to replace it. It appears to be spreading. What can I do? I have the store receipt but not the packaging.

Hi @oberonuk 

Have a word with Sony UK Support . They will confirm your warranty status and let you know what your options are. Have your receipt and serial number ready.
